>
> There is currently an issue where inherit copy() from BaseRelNode. Late in
> our planning process, we attempt to uniqify the graph to ensure that no nodes
> have the same identifier. However, the fact that we aren't implementing copy
> means that we have issues uniqifying. We should add the following method to
> the Prel interface and then implement all required implementations.
> public abstract Prel copy(RelTraitSet paramRelTraitSet, List<RelNode>
> paramList);
